Let me know if this is possible:
I will incorporate next month, something like "Castro Inc" or something along those lines.
I want to start multiple businesses (one at a time of course).
Is it possible to have multiple businesses under my corporate "umbrella"?
For instance, World's Greatest Cleaners, a subsidiary of Castro Inc and Worlds Greatest Billing, a subsidiary of Castro Inc.

I would of course trademark the names in my state.

Is this possible? How would it be possible if they are going to administered through my corporation? Would it be similar to me incorporating myself and owning 2 different franchises? How would it be structured, I know totally separate bookkeeping, but also separate bank accounts?

Please give me a little insight and direction.

Thank you all!
